 ### v1.11.0
 - 📚 Lots of docs improvements! (#650, #623, #616, #609, #606)
 - 🐛 Fix nuget "Package is not found" error on Windows. (#653)
 - ⚠️ cibuildwheel will no longer build Windows 2.7 wheels, unless you specify a custom toolchain using `DISTUTILS_USE_SDK=1` and `MSSdk=1`. This is because Microsoft have stopped distributing Visual C++ Compiler for Python 2.7. See [this FAQ entry](https://cibuildwheel.readthedocs.io/en/stable/faq/#windows-and-python-27) for more details. (#649)
 - 🐛 Fix crash on Windows due to missing `which` command (#641).
 ### v1.10.0
 _22 Feb 2021_
 - ✨ Added `manylinux_2_24` support. To use these new Debian-based manylinux
  images, set your [manylinux image](https://cibuildwheel.readthedocs.io/en/stable/options/#manylinux-image)
  options to `manylinux_2_24`.
 - 🛠 On macOS, we now set `MACOSX_DEPLOYMENT_TARGET` in before running
  `CIBW_BEFORE_ALL`. This is useful when using `CIBW_BEFORE_ALL` to build a
  shared library.
 - 🛠 An empty `CIBW_BUILD` option is now the same as being unset i.e, `*`.
  This makes some build matrix configuration easier. (#588)
 - 📚 Neatened up documentation - added tabs to a few places (#576), fixed some
  formatting issues.

 We're not responsible for errors in those tools, for fixing errors/crashes there. But cibuildwheel's job is providing users with an 'integrated' user experience across those tools. We provide an abstraction. The user says 'build me some wheels', not 'open the docker container, build a wheel with pip, fix up the symbols with auditwheel' etc.  However, errors have a habit of breaking abstractions.

 Linux wheels are built in the [`manylinux` docker images](https://github.com/pypa/manylinux) to provide binary compatible wheels on Linux, according to [PEP 571](https://www.python.org/dev/peps/pep-0571/). Because of this, when building with `cibuildwheel` on Linux, a few things should be taken into account:
- Programs and libraries cannot be installed on the Travis CI Ubuntu host with `apt-get`, but can be installed inside of the Docker image using `yum` or manually. The same goes for environment variables that are potentially needed to customize the wheel building. `cibuildwheel` supports this by providing the `CIBW_ENVIRONMENT` and `CIBW_BEFORE_BUILD` options to setup the build environment inside the running Docker image. See [the options docs](options.md#build-environment) for details on these options.
+- Programs and libraries are not installed on the Travis CI Ubuntu host, but rather should be installed inside of the Docker image (using `yum` for `manylinux2010` or `manylinux2014`, and `apt-get` for `manylinux_2_24`) or manually.

 - The project directory is mounted in the running Docker instance as `/project`, the output directory for the wheels as `/output`. In general, this is handled transparently by `cibuildwheel`. For a more finegrained level of control however, the root of the host file system is mounted as `/host`, allowing for example to access shared files, caches, etc. on the host file system.

 ### Windows and Python 2.7
 Building 2.7 extensions on Windows is difficult, because the VS 2008 compiler that was used for the original Python compilation was discontinued in 2018, and has since been removed from Microsoft's downloads. Most people choose to not build Windows 2.7 wheels, or to override the compiler to something more modern.
 To override, you need to have a modern compiler toolchain activated, and set `DISTUTILS_USE_SDK=1` and `MSSdk=1`. For example, on GitHub Actions, you would add these steps:
 ```yaml
    - name: Prepare compiler environment for Windows
      if: runner.os == 'Windows'
      uses: ilammy/msvc-dev-cmd@v1
      with:
        arch: x64
    - name: Set Windows environment variables
      if: runner.os == 'Windows'
      shell: bash
      run: |
        echo "DISTUTILS_USE_SDK=1" >> $GITHUB_ENV
        echo "MSSdk=1" >> $GITHUB_ENV
    # invoke cibuildwheel...
 ```
 cibuildwheel will not try to build 2.7 on Windows unless it detects that the above two variables are set. Note that changing to a more modern compiler will mean your wheel picks up a runtime dependency to a different [Visual C++ Redistributable][]. You also need to be [a bit careful][] in designing your extension; some major binding tools like pybind11 do this for you.
 More on setting a custom Windows toolchain in our docs on modern C++ standards [here](cpp_standards.md#windows-and-python-27).

    If you have Docker installed, you can locally debug your cibuildwheel Linux config, instead of pushing to CI to test every change. For example:
    ```bash
    export CIBW_BUILD='cp37-*'
    export CIBW_TEST_COMMAND='pytest {package}/tests'
    cibuildwheel --platform linux .

 # GitHub Actions [linux/mac/windows] {: #github-actions}

+To build Linux, Mac, and Windows wheels using GitHub Actions, create a `.github/workflows/build_wheels.yml` file in your repo.
 !!! tab "Action"
    For GitHub Actions, `cibuildwheel` provides an action you can use. This is
    concise and enables easier auto updating via GitHub's Dependabot; see
    [Automatic updates](faq.md#automatic-updates).
    > .github/workflows/build_wheels.yml
    ```yaml
    {% include "../examples/github-minimal.yml" %}
    ```
    You can use `env:` with the action just like you would with `run:`; you can
    also use `with:` to set the command line options: `package-dir: .` and
    `output-dir: wheelhouse` (those values are the defaults).
 !!! tab "pipx"
    The GitHub Actions runners have pipx installed, so you can easily build in
    just one line. This is internally how the action works; the main benefit of
    the action form is easy updates via GitHub's Dependabot.
    > .github/workflows/build_wheels.yml
    ```yaml
    name: Build
    on: [push, pull_request]
    jobs:
      build_wheels:
        name: Build wheels on ${{ matrix.os }}
        runs-on: ${{ matrix.os }}

            with:
              path: ./wheelhouse/*.whl
    ```
 !!! tab "Generic"
    This is the most generic form using setup-python and pip; it looks the most
    like the other CI examples. If you want to avoid having setup that takes
    advantage of GitHub Actions features or pipx being preinstalled, this might
    appeal to you.

 You can also use cibuildwheel directly as an action with `uses: joerick/cibuildwheel@v1.9.0`; this combines the download and run steps into a single action, and command line arguments are available via `with:`.
